Where Sunnova sits
It is a smaller system, serving 2,246 residential customers, which means its fixed costs are spread across a narrow base. At 22.75¢ per kilowatt-hour it is one of the cheaper places to buy electricity in Rhode Island, 22.8% under the statewide average of 29.46¢.
Its customers use very little electricity by national standards, 610 kilowatt-hours a month against 871 nationally. Dense housing, a mild climate or heating that runs on gas rather than electricity all push consumption down, and any of them can leave a household with a modest bill despite a high rate.
That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.
